Answer:
The leftmost graph is a 15 mph rate. Since the biker starts at 0 miles traveled after 0 hours, and the y-value at x=1 hour is 15, you can say that the person biked 15 miles for the hour.
The rightmost graph is a 23 mph rate. The 'distance' from 2 hours to 3 hours is 1 hour; additionally, the 'distance' from 69 miles to 46 miles is 23 miles, so you can see that in the 1 hour of travel, 23 miles have been biked.
Explanation:
In archaeology, rock art is human-made markings placed on natural stone; it is largely synonymous with parietal art. A global phenomenon, rock art is found in many culturally diverse regions of the world. It has been produced in many contexts throughout human history, although the majority of rock art that has been ethnographically recorded has been produced as a part of ritual. Such artworks are often divided into three forms: petroglyphs, which are carved into the rock surface, pictographs, which are painted onto the surface, and earth figures, formed on the ground. The oldest known rock art dates from the Upper Palaeolithic period, having been found in Europe, Australia, Asia and Africa. Archaeologists studying these artworks believe that they likely had magico-religious significance.
